Background Appearing While Form Loads in 11g

We recently upgrades our Forms environment from 10 to 11. Our users have noticed that under Forms 10, when a new form was loaded, the previous form they were using would remain on screen while the new form loaded. In Forms 11 the previous form disappears and the background is displayed while the new form loads.
This has the odd effect of end users now complaining that forms are taking longer to load when in fact they're taking the same time to load as they had in our 10g environment. The users are under the impression that the old forms would load instantaneously because their previous form would remain on screen and the appearance of the background leads them to believe the forms are suddenly not loading instantaneously, but actually taking a couple seconds to load.
